Nowhere is the theory of sympathetic magic more systematically carried into practice for the maintenance of the food supply than in the barren regions of Central Australia. Here the tribes are divided into a number of totem clans, each of which is charged with the duty of propagating and multiplying their totem for the good of the community by means of magical ceremonies and incantations. The great majority of the totems are edible animals and plants, and the general result supposed to be accomplished by these magical totemic ceremonies or _intichiuma_, as the Arunta call them, is that of supplying the tribe with food and other necessaries. Often the rites consist of an imitation of the effect which the people desire to produce; in other words, their magic is of the homoeopathic or imitative sort. [Sidenote: _Intichiuma_, or magical ceremonies for the increase of the totemic animals and plants in Central Australia. Witchetty grub ceremony. Emu ceremony. Hakea flower ceremony. Kangaroo ceremony. Grass seed ceremony.] Thus among the Arunta the men of the witchetty grub totem perform a series of elaborate ceremonies for multiplying the grub which the other members of the tribe use as food. One of the ceremonies is a pantomime representing the fully-developed insect in the act of emerging from the chrysalis. A long narrow structure of branches is set up to imitate the chrysalis case of the grub. In this structure a number of men, who have the grub for their totem, sit and sing of the creature in its various stages. Then they shuffle out of it in a squatting posture, and as they do so they sing of the insect emerging from the chrysalis. This is supposed to multiply the numbers of the grubs.​[291] Again, in order to multiply emus, which are an important article of food, the men of the emu totem in the Arunta tribe proceed as follows. They clear a small spot of level ground, and opening veins in their arms they let the {p86} blood stream out until the surface of the ground, for a space of about three square yards, is soaked with it. When the blood has dried and caked, it forms a hard and fairly impermeable surface, on which they paint the sacred design of the emu totem, especially the parts of the bird which they like best to eat, namely, the fat and the eggs. Round this painting the men sit and sing. Afterwards performers, wearing head-dresses to represent the long neck and small head of the emu, mimic the appearance of the bird as it stands aimlessly peering about in all directions.​[292] Again, men of the hakea flower totem in the Arunta tribe perform a ceremony to make the hakea tree burst into blossom. The scene of the ceremony is a little hollow, by the side of which grows an ancient hakea tree. In the middle of the hollow is a small worn block of stone, supposed to represent a mass of hakea flowers. Before the ceremony begins, an old man of the totem carefully sweeps the ground clean, and then strokes the stone all over with his hands.
